{
linker: align _ramfunc_ram/rom_start/size linker symbol names Cleanup and preparation commit for linker script generator. Zephyr linker scripts provides start and end symbols for each section, and sometimes even size and LMA start symbols. Generally, start and end symbols uses the following pattern, as: Section name: foo Section start symbol: __foo_start Section end symbol: __foo_end However, this pattern is not followed consistently. To allow for linker script generation and ensure consistent naming of symbols then the following pattern is introduced consistently to allow for cleaner linker script generation. Section name: foo Section start symbol: __foo_start Section end symbol: __foo_end Section size symbol: __foo_size Section LMA start symbol: __foo_load_start This commit aligns the symbols for _ramfunc_ram/rom to other symbols and in such a way they follow consistent pattern which allows for linker script and scatter file generation. The symbols are named according to the section name they describe. Section name is `ramfunc` The following symbols are aligned in this commit: - _ramfunc_ram_start -> __ramfunc_start - _ramfunc_ram_end -> __ramfunc_end - _ramfunc_ram_size -> __ramfunc_size - _ramfunc_rom_start -> __ramfunc_load_start Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>
